In Naperville, a Move to the City Can Be a Relocation Case
Downtown Chicago is about 28 miles from Naperville, and 750 ILCS 5/609.2 treats a move of more than 25 miles from a DuPage residence as a relocation. A parent who takes a job in the Loop and wants the children to come along is not simply moving house. That parent needs the other parent’s agreement or a judge’s permission, and the court weighs the reasons for the move, the reasons against it, and what it does to the children’s time with the parent who stays. Naperville cases from the DuPage side of the city are heard at the DuPage County Judicial Center in Wheaton.
Kulerski & Cornelison is a divorce and family law firm in Oakbrook Terrace, a short drive east of Naperville. Kari L. Cornelison has practiced Illinois family law since 1996. She is a court-certified mediator, a trained collaborative lawyer, and an attorney who has tried contested family cases in DuPage County. Those three usually describe three different lawyers. Having done all of it is what makes it possible to say what staying out of court is actually worth in your case.
Why Naperville Clients Work With Us
This firm was built around resolving cases outside a courtroom. That is the practice itself, not a service line held back for clients who think to ask, and it changes what the first meeting is about.
The same few things come up every time:
How Illinois Family Law Applies to a Naperville Case
Illinois has been a no-fault state since 2016. Irreconcilable differences is the only ground, and under 750 ILCS 5/401(a-5), living separate and apart for six months conclusively establishes it. Naperville straddles two counties. Cases from the DuPage side go to Wheaton, the part of the city in Will County is served by the Twelfth Judicial Circuit in Joliet, and venue under 750 ILCS 5/104 follows either spouse’s residence. The same statutes apply on both sides of the line.
The provisions that decide most cases:
Relocation
Governed by 750 ILCS 5/609.2. The parent who wants to move gives written notice, generally at least 60 days ahead. If the other parent objects, the court decides using factors that include the reasons for the move, each parent’s involvement in the children’s lives, the educational opportunities in each place, and whether a workable schedule can survive the distance.
Spousal Maintenance
Set by the guideline formula in 750 ILCS 5/504 when combined gross income is under $500,000, with duration tied to the length of the marriage. When two incomes are close, the guideline can produce little or no maintenance at all, which surprises people who assumed otherwise.
Parental Responsibilities and Parenting Time
Allocated under 750 ILCS 5/602.5 and 602.7, with a parenting plan due within 120 days of service. Naperville is split between District 203 and Indian Prairie District 204, so the school question and the residence question are usually the same question.
Property Division
Equitable, not equal, under 750 ILCS 5/503. For many Naperville couples the largest assets are the house and the retirement accounts, and dividing a 401(k) or a pension takes a qualified domestic relations order in addition to the judgment itself.
Child Support
Calculated under the income shares model in 750 ILCS 5/505 from both parents’ net incomes, with a shared parenting adjustment once each parent has 146 overnights. Childcare, activities and school costs are allocated on top of the base figure, and that part of the order deserves as much attention as the number.
Understanding this at the outset is worth real money. Most of the expensive disputes we see started as a misunderstanding about what the law actually required.
What a Naperville Relocation Case Actually Turns On
Judges do not decide relocation by asking which parent is right. They ask what the move does to the children. A new job with a real increase in pay counts, and so does a concrete plan for how the other parent keeps meaningful time. A move that looks designed to shrink the other parent’s role counts against it. The practical questions matter as much as the legal ones: the drive on I-88 or the BNSF schedule at rush hour, whether weekday overnights survive the distance, which school the children would attend and who pays for the travel. A parent who expects to move should raise it early, ideally in the parenting plan itself, rather than after signing a lease. A parent who receives a relocation notice should take it seriously, because how and when you respond has consequences.
What We Handle for Naperville Clients
We work across the full range of Illinois family law, with the emphasis on resolving matters without a trial wherever the case allows it. Mediation, collaborative divorce, cooperative divorce and one-lawyer divorce are the normal routes here rather than alternatives held in reserve. When a case does have to be litigated, it is handled by an attorney who has actually tried family law cases in DuPage and Cook County.
Where to Start
The earliest choices in a divorce shape everything downstream, and most of them get made before anyone has taken legal advice. A single conversation now is usually the cheapest hour of the whole case.
Common Situations Naperville Families Bring Us
The presenting problem is rarely the actual problem. An argument about a Wednesday overnight is usually an argument about something else, and naming that early tends to shorten the case.
A parent offered a job in the city who wants the children to move too
A house in the District 203 boundary and a new apartment in District 204
Two similar incomes and a disagreement about whether maintenance applies at all
A spouse who will not engage with the process at all
A parenting plan written for toddlers that no longer fits a high school schedule
Each one has a legal answer and a practical answer. Part of the job is telling you when those are different.
How We Work
The route matters more than the argument. Most of the gap between a four month divorce and a two year one is decided at the start, not in a courtroom.
We start with your situation, not your paperwork
What you want the result to look like, and what your spouse is realistically going to do. The second answer shapes everything after it.
We pick a route and price it honestly
Mediation, collaborative, cooperative, one-lawyer or traditional. Each asks something different of you, and some of those demands are uncomfortable enough that clients would rather hear about them now than in month six.
We build the financial record before anyone negotiates
Income, accounts, retirement, the house, the debt. Getting this right at the start is what stops a settlement unraveling two years later.
We document it so it holds
The marital settlement agreement and parenting plan, written to be read years from now by two people who no longer talk much, without a lawyer needed to interpret them.
We will also tell you when your position will not survive contact with a judge. Early, in a meeting that costs a fraction of what a failed hearing would.
Serving Naperville and the Surrounding Communities
Our office is in Oakbrook Terrace, a short drive east of Naperville along I-88. We represent clients throughout DuPage County and into Cook County, including Lisle, Wheaton, Warrenville, Downers Grove, Woodridge, Darien and Westmont. Every DuPage case is heard in the same courthouse in Wheaton, so your address inside the county changes the drive far more than it changes the case.

Meet Attorney Kari L. Cornelison
Kari has practiced family law in the Chicago area since 1996. She is a court-certified mediator, a trained collaborative practitioner, and a divorce litigator with years of trial work in the DuPage and Cook County courts behind her. The trial experience is deliberate rather than incidental. Lawyers who only ever settle tend to overvalue settlement, and lawyers who only ever litigate tend to undervalue it. Having done both, she can tell a Naperville client what a judge in Wheaton is likely to do with a particular set of facts, then leave it to the client to decide whether the offer on the table beats that. Her practice is built around keeping families out of court wherever it is possible, not because litigation never has a place, but because she has watched what a contested divorce does to people and to their children.
What Our Clients Say
“Kari made a stressful process easier to manage. She explained everything clearly and always kept my family’s needs first.”
